ENGINE
I am reporting a potentially recurring safety-related failure of the electric engine coolant/water pump on my 2019 Toyota RAV4 equipped with the 2.5L A25A-FKS engine. My vehicle recently developed DTC P26CB/P26CB71, indicating an electric engine coolant pump performance/speed problem. The failure caused loss of proper coolant circulation and resulted in my vehicle overheating while I was driving on the highway. An unexpected cooling-system failure at highway speed creates a safety hazard and can result in severe engine overheating, potentially catastrophic engine damage, and an unexpected need to stop near traffic. Approximately two months before this failure, my vehicle received a separate cooling-system repair from an authorized Toyota dealer under Customer Support Program 24TE04, which covers the flow shut-off valve/water-bypass assembly on certain 2019–2021 RAV4 vehicles. Approximately two months later, the vehicle developed the P26CB coolant-pump fault. Toyota previously documented electric water-pump problems involving P26CB71 on A25A-equipped vehicles. In Tech Tip T-TT-0614-20, dated May 28, 2020, Toyota identified P26CB71, P26CA14, and P26CA31 and/or coolant leakage from the electric water pump on A25A applications, including the RAV4. Toyota stated the issue was "currently under investigation." Toyota subsequently confirmed to me that the P26CB water-pump issue is separate from the 24TE04 repair and that there is currently no Customer Support Program or warranty extension covering the physical electric coolant pump on my 2019 RAV4. I request that NHTSA review complaint, warranty, repair, and manufacturer data to determine whether premature electric coolant-pump failures involving P26CB/P26CB71 represent a broader safety-related defect trend, particularly in 2019–2021 RAV4 vehicles equipped with the A25A engine, and whether further investigation or corrective action is warranted.
